UPSC Current Affairs 15 September 2026

• The Southern Common Market: MERCOSUR is a South American trade bloc originally established in 1991.
• Member Nations: It comprises Argentina, Brazil, Paraguay, Uruguay, and Bolivia.

• Timeline: The original PTA was signed on January 25, 2004, and officially entered into force on June 1, 2009.
• Limited Scope: Unlike a full Free Trade Agreement, a PTA offers tariff concessions only on a limited "positive list" of goods.
• Current Tariff Lines: Under the current setup, India gives preferential tariff concessions on 450 tariff lines, while MERCOSUR gives concessions on 452 tariff lines.

• Limited Current Coverage: The existing pact excludes services and investments, leaving a vast amount of economic potential untapped.
• Trade Imbalance: Total trade between India and MERCOSUR reached $17.48 billion in 2024-25 ($8.12 billion in Indian exports vs $9.36 billion in imports), with the balance frequently tilted against India.
• Bilateral Targets: Expanding the pact aligns with strategic goals, such as scaling up bilateral trade between India and Brazil alone from $12.2 billion to $20 billion by 2030.

• Export Diversification: It opens up deeper market access for Indian professionals and businesses into Latin America, particularly favouring pharmaceuticals, IT, and engineering exports.
• Strategic Autonomy: A broader deal allows India to secure supply chains and diversify its trade portfolio away from over-reliance on China and Europe.
• Overcoming Trade Barriers: An upgraded FTA is expected to systematically address existing roadblocks for Indian exporters, including high tariff walls, regulatory complexities, and logistical inefficiencies.

• Location & Timeline: The exercise is taking place at the Pokhran Field Firing Range in Jaisalmer, Rajasthan, from September 14 to 16, 2026.
• Participants: More than 20 Indian defence companies, deep-tech start-ups, MSMEs, and Defence Public Sector Undertakings (DPSUs) are actively participating.
• Exhibition Format: The event features both static displays for technological review and live operational demonstrations to evaluate combat readiness.

• Surveillance & Reconnaissance: Testing expendable intelligence-gathering platforms and high-resolution mapping systems.
• Swarm & Autonomous Operations: Evaluating coordinate drone swarms and systems utilizing artificial intelligence (AI) for autonomous navigation without GPS.
• Loitering Munitions: Reviewing indigenous "kamikaze" precision-strike drones.
• Electronic Warfare (EW) & Countermeasures: Testing drone-based jamming capabilities and counter-drone systems designed to neutralize rogue threats.

• Full-Ecosystem Development: In line with the Press Information Bureau, the push for self-reliance (Atmanirbharta) spans the entire drone supply chain—including indigenous airframes, propulsion systems, sensors, payloads, and communications.
• Bridging the Military-Industry Gap: It allows innovators to identify practical capability gaps and refine civilian drone variants for critical infrastructure protection, disaster management, and public safety.
• Youth Engagement: Local students and youth have been invited to view the live demonstrations to inspire interest in aerospace and deep-tech defence manufacturing.

• The Malabari goat is in the news because researchers from the Kerala Veterinary and Animal Sciences University (KVASU) published the first complete mitochondrial genome of this breed in the journal Mammalian Genome.
• The study, published in Springer Nature’s Mammalian Genome, provides molecular evidence that Malabari goats likely reached Kerala by sea via ancient Indian Ocean spice trade routes, unlike most Indian goat breeds that came overland.

• Native Region: Indigenous to the South Malabar region of Kerala, specifically found across districts like Kannur, Kozhikode, Wayanad, Palakkad, Thrissur, and Malappuram. They are also known as Tellicherry or Cutch goats.

• Size: Medium-sized frame; adult females weigh around 30 kg, while males reach about 40 to 41 kg.
• Coat Colour: Highly variable colour patterns, ranging from completely white to solid black, brown, or mixed piebald patterns.
• Beard & Horns: All males and a small percentage of females are bearded. Both sexes feature small, slightly twisted horns pointing outward and upward.
• Ears & Nose: Medium-sized ears directed outward and downward, with a flat or occasionally Roman nose.

• Purpose: Primarily reared for milk and meat production. Their skin is also highly sought after in the leather tanning industry.
• Milk Yield: Produces between 0.5 to 1.5 liters of milk per day, averaging 90 kg over a standard lactation period of 178 days.
• High Reproduction (Prolificacy): Known for multiple births, yielding 50% twinning, 25% triplets, and 5% quadruplets. They reach maturity early (8 to 10 months).

• Climate Resilience: Exhibits exceptional genetic adaptability to survive hot, humid, tropical weather conditions and stressors.
• Major Threat: The primary threat to the breed is genetic dilution caused by the invasive crossbreeding of Boer goats and other non-native breeds entering their breeding tracts.

• Joint Venture: It is a joint initiative rolled out by Kerala's Local Self-Governments (LSG) Department and the General Education Department.
• Aim: The scholarship aims to nurture ecologically sensible citizens, develop green skills, encourage scientific waste management, and inspire students to become ambassadors of clean surroundings.
• Broader Framework: The program operates against the backdrop of the state government’s "Malinyamuktham Navakeralam" (Waste-Free New Kerala) campaign.

• Target Classes: Students of Classes VI, VII, VIII, IX, and XI are eligible to participate.
• Scale: The government targets honouring approximately 46,000 to 50,000 students across the state.

• Financial Incentive: Selected students receive a cash prize of ₹1,500.
• Recognition: Alongside the money, students are awarded an official citation/certificate recognizing them as green leaders.
• School Level Awards: The program also honours schools that show outstanding institutional performance in waste management (e.g., Best Performing School Award).

• Phase 1 Activities: Registered students perform basic ecological tasks, including observing green protocols, segregating waste, practicing biocomposting, conducting waste mapping, and creating videos promoting alternative green products.
• Phase 2 Evaluation: Shortlisted candidates at the Panchayat, Municipal, and Corporation levels progress to a second tier of tasks, which includes auditing commercial or residential areas and visiting waste management plants to draft scientific reports.

• Previous Wins: The department previously won the first prize for the 'Rajbhasha Kirti Puraskar' for two consecutive financial years: 2023–24 and 2024–25.
• Continued Excellence: DARPG secured the top spot once again for the 2025–26 period due to its exceptional efforts in promoting and using Hindi in administrative affairs.
• Leadership Acceptance: The award was physically received by the Secretary of DARPG, Smt. Nivedita Shukla Verma.

• Awarding Body: The honour is conceptualized and presented by the Department of Official Language, which operates under the Ministry of Home Affairs.
• Core Mandate: Active since 1975, the Department of Official Language ensures the systematic promotion and progressive use of Hindi in official Union government communications.

• Hindi Diwas Connection: The award ceremony is deliberately hosted on September 14 every year.
• Constituent Assembly Milestone: This date marks the historic day in 1949 when the Constituent Assembly of India officially designated Hindi written in the Devanagari script as the Official Language of the Union.

• Autoimmune Mechanism: When a genetically predisposed individual eats gluten, the immune system mistakenly attacks its own healthy tissue in the small intestine.
• Villi Destruction: The resulting inflammation flattens the intestinal villi. Without healthy villi, the body cannot absorb vital vitamins, minerals, and macronutrients.
• Hidden Triggers: Gluten hides not just in food (bread, pasta, beer) but also in everyday products like lip balms, toothpastes, cosmetics, and vitamin supplements.

• Gastrointestinal: Chronic diarrhea, abdominal pain, severe bloating, foul-smelling gas, and constipation.
• Systemic & Atypical: Extreme fatigue, iron-deficiency anemia, unexplained weight loss, mouth ulcers, and an intensely itchy skin rash called dermatitis herpetiformis.
• In Children: Stunted growth, delayed puberty, failure to thrive, dental enamel defects, and severe irritability.

• Severe Malnutrition: Leads to fragile bones (osteoporosis or rickets) due to a lack of calcium and vitamin D absorption.
• Reproductive Issues: Increased rates of unexplained infertility and miscarriages.
• Neurological Conditions: Nerve damage leading to numbness or tingling in the hands and feet (peripheral neuropathy), balance issues, or seizures.
• Cancer Risks: Untreated individuals face a four times greater risk of developing small bowel cancers and intestinal lymphomas.
• Secondary Autoimmunity: Higher probability of developing other conditions like Type 1 diabetes or multiple sclerosis.

• Screening: Initial screening is done via an ELISA blood test called the anti-TG IgA test.
• Confirmation: A definitive diagnosis requires an upper gastrointestinal endoscopy with a duodenal biopsy to visually check for tissue damage. Note: Patients must continue eating gluten during the testing phase, or the results may be inaccurate.
• The Only Treatment: Currently, there is no medical cure or pill. The sole treatment is a strict, lifelong gluten-free diet. Following this diet strictly allows the small intestine to heal completely and eliminates the elevated health risks.

• Common Group: Caecilian (a highly specialized group of limbless amphibians).
• Order: Gymnophiona (also known as Apoda).
• Family: Grandisoniidae (some records note Indotyphlidae).
• Genus: Gegeneophis, a genus of caecilians entirely endemic to India.

• Cultural Tribute: The species name chandgadi honours the "Chandgadi language," a distinct local dialect of Marathi spoken in the area where the animal was found.
• Local Contribution: The naming pays tribute to the linguistic heritage and acknowledges local residents whose traditional ecological knowledge directly aided researchers in finding the creature.

• Location: Uncovered in Buzawade village within the Chandgad tehsil of Kolhapur district, Maharashtra.
• Micro-Habitat: Found thriving outside protected forest boundaries, specifically hiding under woodpiles and moist leaf litter in human-inhabited backyard gardens.
• Geographic Range: Endemic to the northern Western Ghats, a globally recognized biodiversity hotspot.
• Research Team: Discovered by a multi-institutional team including the Zoological Survey of India (ZSI), Savitribai Phule Pune University, Yashwantrao Chavan Mahavidyalaya, and the Mhadei Research Centre.

• Worm-like Body: Features a slender, flesh-coloured, cylindrical body that lacks legs, making it easily mistaken for an earthworm or a small blind snake.
• Unique Ring Patterns: Its skin features ring-like folds called annuli. It has primary rings running down its entire length, but its secondary rings are concentrated only on the back half (posterior) of its body.
• Cryptic Diversity: This precise ring pattern is the key feature that distinguishes it from close relatives found in nearby Goa and Amboli.

• Subterranean Lifestyle: It is completely adapted for a fossorial (burrowing) life, spending virtually its entire life cycle deep underground.
• Bio-indicators: Like all caecilians, it has highly sensitive skin, making it a critical bio-indicator for soil health, microclimate shifts, and local habitat degradation.
• Genomic Insights: Genetic testing suggests the northern Western Ghats may hide at least four other unknown lineages of caecilians waiting to be named.
• Conservation Status: Researchers currently recommend listing the species as Data Deficient until wider surveys map out its exact population density and full geographical range.

• Neurological Condition: Cerebral palsy is a group of permanent disorders that affect muscle movement, coordination, and posture.
• Non-Progressive: The underlying brain damage or developmental issue occurs before, during, or shortly after birth and does not worsen over time, though physical symptoms can change as the child grows.
• Clinical Bucket: CP is often treated as a descriptive "bucket" diagnosis because it groups individuals by clinical symptoms rather than a singular root cause.

• Premature Birth: Being born too early or with a very low birth weight remains one of the strongest predictive risk factors.
• Brain Trauma & Infections: Perinatal strokes, severe maternal infections during pregnancy, infant infections, or a severe lack of oxygen during delivery can trigger the condition.
• Genetic Predisposition: Mutations in specific genes disrupt early brain development or leave the infant brain highly vulnerable to environmental stressors.

• Developmental Delays: Infants are typically slow to cross early milestones, such as rolling over, sitting, crawling, or walking.
• Abnormal Muscle Tone: Children experience spasticity (stiff muscles and exaggerated reflexes) or floppiness in their limbs and trunk.
• Movement Impairment: Symptoms include an abnormal walking gait, involuntary trembling, poor fine-motor control, and retained primitive baby reflexes.

• Epilepsy & Seizures: Roughly 25% to 50% of children with CP also suffer from epilepsy, which demands separate, long-term therapeutic care.
• Communication Barriers: Speech and language challenges affect over 75% of children diagnosed with the condition.
• Intellectual Disabilities: Cognitive impairment co-occurs in roughly 45% to 50% of cases, heavily correlated with the severity of the motor disability.
• Orthopedic & Sensory Issues: Chronic pain, progressive joint dislocations, scoliosis, vision issues (like strabismus), and hearing deficits are common secondary challenges.

• Delayed Official Diagnosis: While motor delays surface before age two, formal clinical diagnosis is often deferred until a child is 2 or 3 years old.
• Advanced Testing: Comprehensive diagnostic protocol relies on pediatric neurological exams, brain MRIs to map lesions, and increasingly, targeted genetic sequencing.
• Multidisciplinary Treatment: While there is no cure, a mix of physical therapy, muscle-relaxing medications, specialized walking aids, and early task-specific training significantly boosts independent mobility and lifelong comfort.

• Science-Based Monitoring: The portal acts as a dedicated centralized engine to strengthen data-backed decision-making and scientific evaluation of highly vulnerable coastal habitats.
• Geospatial Mapping: It integrates remote sensing and Geographic Information System (GIS) frameworks to record geospatial data, allowing mapping of canopy density, distribution, and habitat alterations over time.

• Targeted Interventions: The platform hosts essential spatial data to pinpoint critical zones, including ecologically complex territories like the Kori Creek region in Kachchh, which spans 12,450 hectares of the state's restoration layout.
• Site-Specific Planning: It supports conservationists in identifying unique local conditions to execute custom, site-specific restoration methodologies.

• Mangroves Atlas of Gujarat: A comprehensive mapping resource detailing existing spatial variations of the state’s coastline.
• Coffee Table Book on Kachchh Mangroves: Documenting the rich biodiversity and unique environmental landscape of the Kachchh region.

• Community Inclusivity: The tech platform runs parallel to on-ground community-led conservation. (During the event, the Guneri Inland Mangrove Village Biodiversity Management Committee was recognized for preserving the rare Guneri inland mangroves, which became Gujarat’s first Biodiversity Heritage Site in January 2025).
• Livelihood Tracking: The overarching system assists in monitoring programs aimed at generating sustainable livelihoods for local populations, such as seaweed cultivation and allied biodiversity enhancement programs.
